The military felt like a real threat in season 4, with task of finding El and eliminating her. They literally start a shooting at Joyce's house in California just because they found out that El was living there. They feel competent here, whereas in season 5 they were mostly useless and just a nuisance to the rest of the characters.

Sullivan was a great antagonist until they reduced him to whatever that was in season 5.

"Let's try this again, shall we? Where's the girl?"

Every scene with him in season 4 was intimidating. Props to the actor Sherman Augustus.

Also, we see Dr. Sam Owens for the last time in this clip. I guess we'll only find out what happened to him in a future spin-off considering he didn't even show up for the final season.
